DETAILED DESCRIPTION

[0033] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0034] An embodiment of the present invention provides a test fixture bracket, including a bracket body, an upper mold assembly and a lower mold assembly, wherein a lifting drive assembly is configured in the bracket body to drive the upper mold assembly to move between two positions along a set path, wherein when moving to a set position, the upper mold assembly and the lower mold assembly complete the test operation; and quick-release structures are respectively configured on the upper mold assembly and the lower mold assembly, and the quick-release structures can be used to realize rapid disassembly and replacement of modules.

[0035] The following describes in detail the various structures of a test fixture support provided by an embodiment of the present invention, as well as the positional relationship and connection relationship between the various structures, in conjunction with the accompanying drawings.

[0036] like Figures 1 to 9 As shown, the bracket body 10 has a set height, and the bracket body 10 includes a lifting drive assembly 11; the bracket body 10 is a semi-enclosed box structure, and the lifting drive assembly 11 is arranged inside the box structure, the upper mold assembly 20 and the lower mold assembly 30 are located on the same side of the bracket body 10, the upper mold assembly 20 is connected to the lifting drive assembly 11, and the lower mold assembly 30 is connected to the bottom of the bracket body 10; the upper mold assembly 20 and the lower mold assembly 30 are respectively connected to corresponding test modules, and the product to be tested (mainboard) is arranged on the lower mold assembly 30. During the test, the upper mold assembly 20 approaches the lower mold assembly 30, and the two are fitted to complete the test operation. For example, the test method adopts a pin insertion test. After the test is completed, the upper mold assembly 20 is reset, and the next product to be tested is replaced, and the above test action is repeated.

[0037] In the above-mentioned testing method, the upper mold assembly 20 is driven to rise and fall by the lifting drive assembly 11, so that the upper mold assembly 20 moves between the first position and the second position. When the upper mold assembly 20 is at the first position, the upper mold assembly 20 and the lower mold assembly 30 are in contact with each other. When the upper mold assembly 20 is at the second position, the upper mold assembly 20 and the lower mold assembly 30 are separated.

[0038] Based on this, by using the lifting drive component 11 to repeatedly control the lifting operation of the upper mold component 20, the automated testing of multiple products to be tested can be automatically completed. In this way, there is less manual intervention, which can reduce the labor input cost, and the mechanized motion operation has higher efficiency and accuracy.

[0039] Continue to refer Figures 1 to 9 As shown, in the embodiment of the present invention, the lifting drive assembly 11 includes a driving shaft structure 111, a connecting rod structure 112 and a guide structure 113; the driving shaft structure 111 includes a shaft body 1111 and a driving member 1112, the driving member 1112 is connected to the shaft body 1111, and drives the shaft body 1111 to rotate; the connecting rod structure 112 can be extended or contracted in a set manner, wherein the driving shaft structure 111 is provided with power for the connecting rod structure 112, that is, the driving member 1112 drives the shaft body 1111 to rotate, so as to realize the driving of the connecting rod structure 112.

[0040] For example, the driving member 1112 includes a servo motor 11121, a driving wheel 11122, a transmission belt 11123 and a power wheel 11124; the output shaft of the servo motor 11121 is connected to the driving wheel 11122, the power wheel 11124 is fixedly mounted on the rotating shaft body 1111, the driving wheel 11122 and the power wheel 11124 are connected by the transmission belt 11123, and the servo motor 11121 drives the transmission belt 11123 to rotate, thereby driving the power wheel 11124 and the rotating shaft body 1111 to rotate.

[0041] The servo motor 11121 rotates, driving the driving wheel 11122 to rotate, the driving wheel 11122 drives the transmission belt 11123 and the power wheel 11124 to rotate, and the power wheel 11124 drives the rotating shaft body 1111 to rotate. The servo motor 11121 is used to control the rotation accuracy of the rotating shaft body 1111, and the rotation direction of the rotating shaft body 1111 can be controlled by controlling the forward rotation or reverse rotation of the servo motor 11121, thereby controlling the extension or contraction of the connecting rod structure 112. For example, the servo motor 11121 is fixedly arranged at the bottom of the bracket body 10.

[0042] In the embodiment of the present invention, the driving of the rotating shaft body 1111 is not limited thereto, and other driving forms that can drive the rotating shaft body 1111 to rotate may also be adopted.

[0043] Continue to refer Figures 1 to 9As shown, the connecting rod structure 112 includes a first connecting rod 1121, a second connecting rod 1122 and a third connecting rod 1123, one end of the first connecting rod 1121 is fixedly connected to the rotating shaft body 1111, one end of the second connecting rod 1122 is rotatably connected to the other end of the first connecting rod 1121, the other end of the second connecting rod 1122 is rotatably connected to one end of the third connecting rod 1123, the upper mold assembly 20 is connected to the second connecting rod 1122, and the other end of the third connecting rod 1123 is connected to the guide structure 113.

[0044] For example, in the initial state, the upper mold assembly 20 is located at the second position, that is, separated from the lower mold assembly 30, and the upper mold assembly 20 needs to move to the first position under the drive of the lifting drive assembly 11. The driving member 1112 drives the rotating shaft body 1111 to rotate. Since one end of the first connecting rod 1121 is fixedly connected to the rotating shaft body 1111, the first connecting rod 1121 rotates synchronously with the rotating shaft body 1111. As the first connecting rod 1121 rotates, the connection position of the first connecting rod 1121 and the second connecting rod 1122 swings, and the connection position of the second connecting rod 1122 and the third connecting rod 1123 swings. Finally, the other end of the third connecting rod 1123 is driven to rise and fall along the set path. Among them, the upper mold assembly 20 is connected to the second connecting rod 1122, and the swing amplitude of the second connecting rod 1122 completes the switching of the upper mold assembly 20 between the first position and the second position.

[0045] In the embodiment of the present invention, the number and swing path of the connecting rod structure 112 are not limited thereto. On the basis of satisfying the movement of the upper mold assembly 20 between the first position and the second position, other connecting rod forms can also be used.

[0046] In the connecting rod structure 112 described above, the third connecting rod 1123 swings, and the other end of the third connecting rod 1123, i.e., the end away from the second connecting rod 1122, slides along a set path in the guide structure 113. The set path limits the swinging path of the third connecting rod 1123 and the second connecting rod 1122, thereby limiting the connecting rod structure 112 to the desired path range.

[0047] As shown in the figure, the guide structure 113 includes a first guide groove 1131 arranged along the lifting direction, and the other end of the third connecting rod 1123 is located in the first guide groove 1131 and is used to slide along the lifting direction. For example, a slider is arranged at the other end of the third connecting rod 1123, and the slider is arranged in the first guide groove 1131, and the other end of the third connecting rod 1123 slides in the first guide groove 1131 through the slider.

[0048] For example, the bracket body 10 includes two parallel and spaced-apart vertical plates 12, the rotating shaft body 1111 is rotatably connected to the vertical plates 12 through a bearing, and the first guide groove 1131 is provided on the vertical plate 12; the guide structure 113 also includes a second guide groove 1132, the second guide groove 1132 is provided on the vertical plate 12, and the second guide groove 1132 is connected to the first guide groove 1131; a sliding member 1124 is provided at the connection between the second connecting rod 1122 and the third connecting rod 1123, the sliding member 1124 is located in the second guide groove 1132, the sliding member 1124 slides along a set arc, and the second guide groove 1132 is arc-shaped.

[0049] Driven by the rotating shaft body 1111, the connection between the second connecting rod 1122 and the third connecting rod 1123 first moves in an arc path, and then moves in a vertical lifting and lowering movement path. Therefore, a second guide groove 1132 connected to the vertical plate 12 can be set. The second guide groove 1132 guides when the connection between the second connecting rod 1122 and the third connecting rod 1123 moves in an arc path. The second guide groove 1132 is connected to the first guide groove 1131, and the connection between the second connecting rod 1122 and the third connecting rod 1123 will also move into the first guide groove 1131, and it and the other end (slider) of the third connecting rod 1123 can slide synchronously in the first guide groove 1131, that is, the first guide groove 1131 has sufficient length to meet the sliding guide requirements.

[0050] Continue to refer Figures 1 to 9 As shown, in the embodiment of the present invention, the lifting drive assembly 11 also includes a guide column 114, a lifting block 115 and a telescopic member 116; one end of the guide column 114 is vertically connected to the bottom of the bracket body 10, the lifting block 115 is sleeved on the guide column 114, and a telescopic member 116 is arranged between the lifting block 115 and the bottom of the bracket body 10, the lifting block 115 includes a guide edge 1151, and one end of the second connecting rod 1122 abuts against the guide edge 1151; when the lifting drive assembly 11 descends, one end of the second connecting rod 1122 slides along the guide edge 1151 and drives the lifting block 115 to descend along the guide column 114; when the lifting drive assembly 11 rises, the telescopic member 116 drives the lifting block 115 to rise and reset, one end of the second connecting rod 1122 slides along the guide edge 1151, and the lifting block 115 lifts the second connecting rod 1122 to rise and reset.

[0051] Among them, the guide edge 1151 is a bevel structure. For example, a roller is arranged at the connection between the second connecting rod 1122 and the third connecting rod 1123, and the roller is in contact with the guide edge 1151. During the descent, the guide wheel rolls along the guide edge 1151 and presses the lifting block 115 downward. The lifting block 115 slowly moves downward under the action of the telescopic member 116, thereby realizing the slow descent of the upper mold assembly 20. By arranging the guide column 114, the lifting block 115 and the telescopic member 116 and other structures, a damping effect is played to prevent the lifting drive assembly 11 from being lifted too quickly, and to prevent contact or collision between the structures, so as to improve the lifting stability of the upper mold assembly 20 and protect the structural parts.

[0052] For example, the telescopic member 116 includes a telescopic spring, which is sleeved on the guide column 114, and one end of the telescopic spring abuts against the lifting block 115, and the other end abuts against the bottom of the bracket body 10. When the lifting block 115 descends, the telescopic spring is compressed and deformed, and when the lifting block 115 rises, the telescopic compression spring 454 is reset to assist in lifting the lifting block 115 to move upward.

[0053] For example, the lifting drive assembly 11 further includes a vertical slide rail 117, which is located on one side of the guide column 114 and vertically connected to the bottom of the bracket body 10, and the lifting block 115 is slidably connected to the vertical slide rail 117. The lifting block 115 regularly reciprocates on the vertical slide rail 117 along the length direction of the slide rail, which can improve the stability of the lifting block 115 and the accuracy of the lifting position.

[0054] Continue to refer Figures 1 to 9 As shown, in the embodiment of the present invention, the upper mold assembly 20 includes an upper frame mounting plate 21 and an upper mold frame 22, and the lower mold assembly 30 includes a lower frame mounting plate 31 and a lower mold frame 32. The upper frame mounting plate 21 is connected to the lifting drive assembly 11, and the lower frame mounting plate 31 is connected to the bracket body 10; the upper frame mounting plate 21 and the upper mold frame 22, the lower frame mounting plate 31 and the lower mold frame 32 are respectively detachably connected via a quick-change structure 40.

[0055] Among them, the upper mold assembly 20 and the lower mold assembly 30 are used to test one or a type of mainboard. The modules connected to the current upper mold assembly 20 and the lower mold assembly 30 are suitable for the current applicable mainboard model test. When a different model of mainboard test is required, the corresponding module can be replaced, and the module can be disassembled and assembled through the quick-change structure 40.

[0056] For example, the quick-change structure 40 includes a first connecting frame 41, a second connecting frame 42, a sliding rod 43 and a connecting column 44, the sliding rod 43 is slidably connected to the first connecting frame 41, and the connecting column 44 is vertically arranged on the second connecting frame 42; wherein, the first connecting frame 41 or the second connecting frame 42 can be arranged on the upper frame mounting plate 21 or the lower frame mounting plate 31, or can also be arranged on the upper mold frame 22 or the lower mold frame 32; or, for example, the first connecting frame 41 or the second connecting frame 42 is a part of the upper frame mounting plate 21, the lower frame mounting plate 31, the upper mold frame 22 or the lower mold frame 32.

[0057] The sliding rod 43 includes a through hole 431, and the first connecting frame 41 is provided with a through hole 411, the through hole 431 and the through hole 411 overlap, the through hole 431 includes a connecting portion 4311 and a locking portion 4312, and the top of the connecting column 44 includes a nail cap 441; when the quick-change structure 40 is connected, the first connecting frame 41 and the second connecting frame 42 fit together, at this time, the nail cap 441 of the connecting column 44 passes through the through hole 411 and the connecting portion 4311 in sequence, and the outer diameter of the nail cap 441 is smaller than the inner diameter of the connecting portion 4311, which can be Ensure the smooth passage of the top cap and the connecting column 44; then, the sliding rod 43 slides on the first connecting frame 41, and the sliding direction is the direction from the connecting part 4311 to the locking part 4312. The locking part 4312 slides to the position of the connecting column 44 and is overlapped with the nail cap 441. The hole diameter of the locking part 4312 is smaller than the outer diameter of the nail cap 441. In this state, along the axial direction of the connecting column 44, the relative position of the sliding rod 43 and the first connecting frame 41 is limited, and the two cannot be separated, thereby achieving the purpose of connection.

[0058] For example, a strip hole is provided on the sliding rod 43, and a limiting protrusion is provided on the first connecting frame 41, and the limiting protrusion is inserted into the strip hole. When the sliding rod 43 slides, the limiting protrusion slides in the strip hole, wherein the sliding stroke of the limiting protrusion in the strip hole satisfies the stroke from the connecting part 4311 to the locking part 4312.

[0059] In order to further limit the relative position between the sliding rod 43 and the first connecting frame 41, the quick-change structure 40 also includes a locking structure 45, which includes a locking piece 451 and a locking hole 452; the locking piece 451 is arranged on the sliding rod 43, and the locking hole 452 is arranged on the first connecting frame 41. The locking piece 451 slides synchronously with the sliding rod 43. When the locking part 4312 slides to the position of the connecting column 44, the locking piece 451 is connected and locked with the locking hole 452.

[0060] For example, a locking frame 453 is provided on the sliding rod 43, and the locking frame 453 includes a spring 454. The locking piece 451 is columnar, and the spring 454 is sleeved on the locking piece 451. As shown in the figure, in the non-locking state, the spring 454 is compressed, and the locking piece 451 is separated from the locking hole 452. The sliding rod 43 and the first connecting frame 41 can slide relative to each other. When in the locking state, under the action of the elastic force of the spring 454, the locking piece 451 is moved toward the direction of the first connecting frame 41, and its end is inserted into the locking hole 452, thereby completing the locking operation.

[0061] The embodiment of the present invention also provides a test fixture, including the above-mentioned test fixture bracket. The test fixture also includes multiple groups of test modules, configured with a set of test fixture brackets, and the corresponding test modules are selected according to the model of the product to be tested, and the test modules are quickly replaced with the test fixture brackets through the quick-change structure 40.
